HI! I am actually working with the library for arduino of RAK811 modem, for second band of us915 frecuency and ABP mode. The module works fine; but i have some doubs about "fCnt". The fCnt that i receive is always on "0". I think that maybe one of the next commands maybe restart the counter:
2- at+set_config=dev_addr:" + DevAddr + "&nwks_key:" + NwkSKey + "&apps_key:" + AppSKey?
can you tellme wich are?
@leopold When we opened and used the GPS tracker for first few times, the GREEN LED was always flashing. never stopped. And now it doesnt flash at all, since it still run the same code that device was shipped with, it shouldnt have stopped flashing ? From your description, Green LED should be flashing on turning on tracker, but it doesnt.
